bad service

I'm very disappointed with the way Momentum has handled my account during COVID. I called in April and requested to utilize my premium skip and I got confirmation that it was approved....however on the 27th of April my account was debited so I called my bank to reverse the transaction. 2 months later I call Momentum to find out why they have not been taking they money and was told that I no longer had a policy with them. How can you cancel my policy with out even contacting me? Also why did you debit my account when you clearly stated on email that my premium skip was actioned? This needs to be sorted out as soon as possible, I have never missed a payment and now suddenly you cancel without letting me know.
